To all whom it may concern 3 Be it known that I, J PEAnL NVILsoN, citizen of the United States. residing at Jacksonville, inthe county of Duval and State of Florida, have invented certain new and useful Improvements in Finger-Bars, of which the following is a specification. 1 My invention relates to "an improvement in finger-bars for feeding-battens to be used in the manufacture of wire-bound boxes and crates, and this bar is extensible in order to make it adaptable to boxes of different lengths, and is adapted to be usedin connection with fingers secured thereto, each lot which engage a batten one at a time, forcing it from the bottom of the hopper into position on the veneer preparatory to itsbeing secured thereto, after which the bar is automatically released and returns to a position to move forward-another set of battens, andsoon. i In the accompanying drawings Figure 1 is a view in side elevation, Fig. 2 is a plan view; Fig. 3 is an end view; Fig. I is a fragmentarydetail the lug-releasing mechanism;

Fig. 5 is a modified formof clamping means permitting adjustment of the finger bars and of the fingers with respect to said bars:

Fig. 6 is a top plan view of the same; Fig. 7 is an end view of the same; and

view of Fig. 8 is a view of an adjustable stopjwith a resilient bumper mounted therein, being engaged by one end of the finger-bar.

The finger-bar 1 is extensible and is preferably composed of three sections, namely a central section 1, and two end sections 2, 2. These are provided with slots 3, 3, extending longitudinally thereof, and the bolts 1, 4:, with nuts 5 thereon hold the finger-bar in its lengthened or shortened adjustment.

The fingers 6, 6, three being shown, although the number might, of course, be varied, are securely bolted as at 7, 7 to the finger-har. These fingers extend forwardly and are each provided with a lug 8, adapted to extend through an opening in the front of the batten-hopper 9, whereby each finger is adapted to engage and move forward a single batten 30 from the hopper bottom at a time.

The ends of the two outer finger-bars rest and slide upon the upper edge of the T- irons I0 10, of the frame, as shown in: Fi

mitting itto move in the direction of the len th of the fingers.

111e veneer-slats 12, 12 rest at their ends upon theinwardly-extending flanges 13, 13, of theTdrons, as shown in Fig. 3, andthese slats are fed forwardly beneath the battens, as shown in Fig. .1,by the lugs 14, 15, 16, 17 and 18 on theendless chains 19, 19, of which there are two in the machine illustrated, the chain traveling through channels 20, 20, provided therefor, which channels also provide an intermediate support beneath the veneer-slats. At intervals, a lug is higher than the rest, as at 15', so as to travel in the path of a trip 21 extending downwardly from the finger-bar, as shown in Figs. 1, 3 and 4,'thus carrying the finger-'bariwith the fingers forwardthrough the openings in the bottoms of the hoppers to remove a batten from each hopper and leave them in position transverselyfupon the veneer slats, ready to be stapled] or otherwise secured thereto. This movement of the fingenbar continues until the roller 22 on the trip ridesup upon the wedge shaped[projection 23 fastened to the hopper, which-byengaging the roller lifts the trip, as shown in Fig. 4, against the action of the springs 24:, 24 on either side thereof, removing the tripfrom the path of the lug 15, which latter continues on, whereupon the finger-bar is automatically returned to its normal position by the spiral springs 25, 25.

In the construction hitherto described, the fingers are bolted rigidly to the finger-bar. It is perfectly possible to adjust these in two ways. namely along the finger-bar to bring them nearer together, and also lengthwise to shorten the fingers as shown in Figs. 5. 6 and 7, in which a clam 25 embraces the finger-bar and fingers at their point of intersection, the fingers passing through the slots 26, 26, in the opposite sides of the clamp, and the screws 27, 27, being provided to hold them rigidly in their adjusted position.

It should be mentioned that one at least of the T-rails 10 of the frame is adjustable. and can be moved to any position desired within the width of the stapling machine being used. Ordinarily one T-rail is stationary.

hen. desired to make a wider or narrower box-web, the adjustable T-rail is set to the In F ig. 8, a sto 28 isydisclosedias.having a resilient :bumper 30 mounted in one side thereof, adaptedto be engaged by-oneiend of the finger-bar -2-for taking up lithe shock of its return to its normalposition.

2. In aimachine for feeding slatsafidbab tens, thecombination witha hopper having a tapering projection, and an endless chain carrying lugs thereon I of different ,lengths, said lugs being in position'to feed-the slats, of afingerbar, a spring-actuated t'rip connected with the finger-bar and fin position normally to be engaged by one of the lugs,

3., In a machine for feeding slats and bat tens, the combination with a slidab-le fingerbar carrying. fingers and trips, of endless chains carrying lugs which feed the slats to form a box or crate, certain lugs being arranged to :move in the path of the trips to carry the finger-bar forward and cause the fingers to feed forward a batten, means'for automatically releasing the trip, and means for returning the finger-bar to its normal position.

4.

V i 5. In amachine for feeding slats andbattens, the combination witha finger-bar, fingers adjustably secured to the finger-bar, trips on the finger-bar, movi11g devices having lugs for feedingthe slats, certain of. said lugs being arranged to move Lin the path of the trips on the finger-bar tocarrvthe latter forward and cause a batten to be fed for- Ward by the fingers, and means for automatically returning the finger-bar to its normal position.
